Summary

Baphia rosa Mackinder & R. Clark is described as new and illustrated. The species is known from a single collection from the Kabompo District of NW Zambia and is assessed here as Vulnerable (Vu D2) under the criteria of IUCN. An updated key to the species of Baphia in the Flora Zambesiaca region is provided. We judge B. rosa as closest morphologically to B. chrysophylla and propose that B. claessensii, previously classified as a subspecies of B. chrysophylla be reinstated at specific rank. We suggest that true B. chrysophylla is known only from a population at Mukenge in SE Democratic Republic of Congo. Whilst we speculate that some collections currently identified as B. chrysophylla may represent B. gilletii, we maintain B. gilletii in synonymy under B. chrysophylla due to insufficient evidence to reinstate the former as a distinct species. A distribution map of all taxa included in this study is provided.

Notes

  1. After the current study was submitted for publication, a new taxonomic account of Baphia was published by Goncharov et al. (2011) in which limited changes to the existing taxonomy of Soladoye (1985) were included. The proposed changes do not affect the findings presented in our paper.
